Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts

Bulletins 4000 -

Sheep mortality during the first year of life is a large problem on many farms and poses a significant animal welfare issue for Australian agriculture. Post weaning mortality is estimated to cost the Australian sheep industry more than $89 million annually through reduced income, poor productivity and increased management expenses (Sackett et al. 2006).

A high mortality rate among weaners reduces the number of surplus animals available for sale and the number of potential breeding replacements. This, in turn, affects the selection intensity for desirable traits and the flock’s rate of genetic improvement.

Ill thrift and poor growth of weaner …

Temperature Influence And Heat Management Requirements Of Microalgae Cultivation In Photobioreactors, Thomas Hagen Mehlitz

Master's Theses

Microalgae are considered one of the most promising feedstocks for biofuel production for the future. The most efficient way to produce vast amounts of algal biomass is the use of closed tubular photobioreactors (PBR). The heat requirement for a given system is a major concern since the best algae growth rates are obtained between 25-30 °C, depending on the specific strain. A procedure to determine temperature influence on algal growth rates was developed for a lab-scale PBR system using the species Chlorella. A maximum growth rate of 1.44 doublings per day at 29 °C (optimal temperature) was determined. In addition, …

Extending Grazing And Reducing Stored Feed Needs, Don Ball, Edward N. Ballard, Mark Kennedy, Garry D. Lacefield, Dan Undersander

Forage Symposium at the Kentucky Cattlemen’s Convention

Why extend the grazing season? For most livestock producers, extending the grazing season for their animals, or otherwise filling gaps in pasture forage availability to reduce stored feed needs, should be a high priority objective.

Teff: What Is It? Where Does It Fit In Kentucky, Bret Winsett

Forage Symposium at the Kentucky Cattlemen’s Convention

Teff (Eragrostis tef (zucc)) is an annual, warm season grass native to Ethiopia. Throughout its history, teff has been used more as a gluten-free grain for flour than as forage. However, in recent years, forage agronomists and producers have become increasingly interested in its potential contribution as a hay crop. Teff is characterized by a fairly large crown, many tillers, fine stems, a very shallow root system, rapid growth and high tonnage capability. During the vegetative stage, teff plants look somewhat similar to tall fescue in size and color. Teff tends to germinate quickly with good moisture, regrow quickly after …

Weed Control Options For Pastures, Jon Doran

Forage Symposium at the Kentucky Cattlemen’s Convention

What is a weed? A pasture or hayfield “weed” is any plant that you deem as being out of place and/or a plant that is decreasing your desired forage production. Weeds may be classified in several ways including broadleaf weeds, woody plants, and undesirable grasses. Besides decreasing forage, weeds can also interfere with forage utilization, grazing distribution, etc. There are several methods available to control weeds and increase production of and access to desirable forages. The three main methods are cultural, mechanical, and chemical. The cultural method is quite simple-a thriving grass stand is an excellent form of weed control …

Selecting Clover Varieties Wisely, S. Ray Smith

Forage Symposium at the Kentucky Cattlemen’s Convention

Although there are not a lot of new red clover varieties, several companies and Universities have active red clover breeding programs. In some ways, red clover is the easiest species to make variety recommendations for. Simply put, “only plant certified seed of improved varieties, never plant common seed.” University of Kentucky research has shown that the difference between improved varieties and common seed can be 6000 to 10,000 lb/acre in higher yield and 1 to 1 ½ years longer stand life. Sometimes you may “luck up” and find that the bag of cheap common seed you purchased was actually an …

Severity Of Root Rot In Mature Subterranean Clover And Associated Fungal Pathogens In The Wheatbelt Of Western Australia, Tim Scanlon, Tiernan A. O’Rourke, Martin J. Barbetti, Megan H. Ryan, Len J. Wade, Alan C. Mckay, Ian T. Riley, Hua Li, Krishnapillai Sivasithamparam

Journal articles

Pasture decline is considered to be a serious challenge to agricultural productivity of subterranean clover across southern Australia. Root disease is a significant contributing factor to pasture decline. However, root disease assessments are generally carried out in the early part of the growing season and in areas predominantly sown to permanent pastures. For this reason, in spring 2004, a survey was undertaken to determine the severity of root disease in mature subterranean clover plants in pastures located in the wheatbelt of Western Australia. DNA-based soil assays were used to estimate population density in the soil of a variety of soil-borne …

Current And Potential Distributions Of Three Non-Native Invasive Plants In The Contiguous Usa, Chad C. Jones, Sarah Reichard

Botany Faculty Publications

Biological invasions pose a serious threat to biodiversity, but monitoring for invasive species is time consuming and costly. Understanding where species have the potential to invade enables land managers to focus monitoring efforts. In this paper, we compared two simple types of models to predict the potential distributions of three non-native invasive plants (Geranium robertianum, Hedera spp., and Ilex aquifolium) in the contiguous USA. We developed models based on the climatic requirements of the species as reported in the literature (literature-based) and simple climate envelope models based on the climate where the species already occur (observation-based). We then compared the …

Dispersal And Establishment Both Limit Colonization During Primary Succession On A Glacier Foreland, Chad C. Jones, Roger Del Moral

Botany Faculty Publications

Plant colonization can be limited by lack of seeds or by factors that reduce establishment. The role of seed limitation in community assembly is being increasingly recognized, but in early primary succession, establishment failure is still considered more important. We studied the factors limiting colonization on the foreland of Coleman Glacier, Washington, USA to determine the importance of seed and establishment limitation during primary succession. We also evaluated the effects of seed predation, drought and existing vegetation on establishment. We planted seeds of seven species into plots of four different ages and found evidence that both seed and establishment limitation …

Characterizing Bentgrass Distribution With Spatial And Biological Data To Support Ecological Risk Assessment In Connecticut, Carol Auer, Collin Ahrens, Jinwon Chung, Thomas Meyer

Plant Science Presentations and Proceedings

Genetically-modified (GM) crops must be assessed before they are released into the environment. Our research examines the potential for gene flow and negative ecological impacts from the release of GM turfgrasses. Gene flow can produce hybrid offspring with transgenes and novel traits that could change the ability of the plant to survive and spread. If hybrid offspring have an advantage in the environment, they could become invasive and/or affect other components of our ecosystems. Creeping bentgrass (Agrostis stolonifera) is a common, non-native turfgrass that is a weed and could hybridize with other Agrostis species. At present, United States Department of …

Good Agricultural And Handling Practices For Grapes And Other Fresh Produce, Pamela L. Brady, Justin R. Morris

AAES Research Reports and Research Bulletins

In recent years consumption of fresh fruits and vegetables has increased dramatically. This trend has increased the amount of produce being purchased at farmer’s markets, road-side stands, and neighborhood markets since consumers say they feel that the direct contact with growers at these markets makes them better able to assess the quality and safety of the produce. This buying trend has opened new markets to small- and medium-sized farms, which sell at these local outlets.

Impacts Of Tamarisk Biocontrol (Diorhabda Elongata) On The Trophic Dynamics Of Terrestrial Insects In Monotypic Tamarisk Stands, Stephanie Michelle Carroll Strudley

Electronic Theses and Dissertations

Combating tamarisk (Tamarix spp.), an exotic tree species that has invaded 1-1.6 million hectares of riparian land in the Midwestern United States, with the introduced leaf beetle Diorhabda elongata provides an opportunity to evaluate how the trophic spectra of terrestrial insects respond to a herbivorous biocontrol. To evaluate this restoration approach and the interaction biocontrol may have with terrestrial insect populations, I quantified trophic unit richness and abundance and common family abundance of resident insect populations while also measuring biocontrol abundance and status during the previous season (present or not present). These measurements were taken four times throughout one …

Curing Nature-Deficit Disorder: How Environmental Education Helps Kids Learn, Jamie Leigh Langley

Mahurin Honors College Capstone Experience/Thesis Projects

Walk into any public school and talk with the children about their experiences in nature and you will begin to see a pattern. Children have made few connections with the world around them. They do not spend much time outdoors and the time they do spend outdoors is not spent interacting directly with nature. Why does this matter? Look at these same kids and you will see another pattern emerging: Attention-Deficit Disorder, depression, obesity, emotional problems, etc. While not all of these problems are directly caused by a lack of interaction with the natural world, current research shows that there …

Roadmap For Future Research On Plant Pathogen Effectors, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

Bacterial and eukaryotic plant pathogens deliver effector proteins into plant cells to promote pathogenesis. Bacterial pathogens containing type III protein secretion systems are known to inject many of these effectors into plant cells. More recently, oomycete pathogens have been shown to possess a large family of effectors containing the RXLR motif, and many effectors are also being discovered in fungal pathogens. Although effector activities are largely unknown, at least a subset suppress plant immunity. A plethora of new plant pathogen genomes that will soon be available thanks to next-generation sequencing technologies will allow the identification of many more effectors. This …

The 2008 Update Of The Aspergillus Nidulans Genome Annotation: A Community Effort, Jennifer Russo Wortman, Steven D. Harris, Geoffrey Turner, Aspergillus Nidulans Consortium

Center for Plant Science Innovation: Faculty Publications

The identification and annotation of protein-coding genes is one of the primary goals of whole-genome sequencing projects, and the accuracy of predicting the primary protein products of gene expression is vital to the interpretation of the available data and the design of downstream functional applications. Nevertheless, the comprehensive annotation of eukaryotic genomes remains a considerable challenge. Many genomes submitted to public databases, including those of major model organisms, contain significant numbers of wrong and incomplete gene predictions. We present a community-based reannotation of the Aspergillus nidulans genome with the primary goal of increasing the number and quality of protein functional …
